Hello DeadKoby -
Lately I've been on something of a cap-testing pilgrimage, watching a lot of YouTube videos on the subject. Apparently I've been doing it inadequately all this time. It seems there is no all-in-one tester that can tell everything you need to know about a cap for a given application. ESR, leakage @ rated voltage, value, etc. I don't own the right equipment and it looks like you need hundreds of dollars of test gear to make it happen.
Just curious - how did you test your Kustom's tantalums? I've always heard they had a bad rep in certain applications. I've never used them in my own designs. The only place I recall them being specified was in data sheets for bypass caps on monolithic voltage regulator ICs. Also, aren't modern Aluminum 'lytics a lot better than they were in the late 60's? I assume Kustom's engineers spec'd the Tants for a reason, but maybe the performance gap has closed somewhat by now?
All I have is a cap meter to read value - I don't have an ESR or a leakage tester. A friend loaned me an old Heathkit IT-28 but it's a little rusty and could use a rebuilding.
I will be less lazy and track down the real cause of the DC offset, I promise!
Regards,
Dave
